The article presents a description of a computer simulator of a technologist's automated workplace for designing technological processes of magnetic-pulse metal processing (MPMP). The simulator was based on an automated information system (AIS) for calculating the parameters of the MPMP processes, which includes a new universal method for calculating the parameters of the MPMP. This method has 4 stages. At the first stage, the mechanical characteristics of the process are calculated, which makes it possible to determine the specific features of the technological operation being performed. These features refer to the work of deformation of the workpiece, the kinetic energy of the deformed section of the workpiece, the magnitude of the pressure of the pulsed magnetic field (PMF), the relationship between the amplitude value of the PMF pressure and the oscillation frequency of the discharge current. At the second stage, a magnetic-pulse installation (MPI) is selected. At the third stage, the parameters of the inductor system are calculated, including the choice of the pitch and the number of turns of the inductor. The initial data for the calculation are the length of the inductor, the intrinsic inductance of the MPI, the dimensions of the workpiece, and the specific electrical conductivity of the materials of the inductor and the workpiece. The fourth stage is the calculation of the MPMP mode, which consists in determining the discharge energy MPI. The LS-DYNA software package is used to visualize the process. The computer simulator is intended for use in the educational process and in production for retraining of personnel, advanced training or certification. |
